2 Claims.

This invention relates to a carton, and particularly to a carton made offibrous material for packaging ice cream and other comestibles.

The present invention contemplates a carton construction provided withmeans for readily opening the same so as to make the contents accessiblewithout any attendant peeling or tearing of the fibrous material fromwhich the carton is made.

An object of the invention is to provide a carton for ice cream and thelike which when opened may be spread out fiat so as to completely exposethe frozen contents of the package for slicing or removal as a whole.

A further object of the invention is to'provide a carton for ice creampackaging which is formed from a single blank of board scored and foldedto provide a carton with interlocking ends so arranged and associatedwith respect to the cover that when the cover is opened the whole cartonwill open exposing the contents for slicing or removal as a unit.

A still further object of the invention is to provide a carton formedfrom a single blank of thin board material scored and folded in a boxform and provided with a flap which is glued to close the carton andwhich can be readily grasped and torn open to expose the carton forremoval of its contents.

Further advantages and details will be apparent from the accompanyingdrawings in which:

Figure 11 is a front view of the sealed carton made from the blankillustrated in Figure 10,

Figure 12 is a sectional view taken on lines i2-|2 of Figure 11.

Referring to the drawings, the carton is made from a single blank ofpaper board which is preferably impregnated or coated with" paraffinwax. The blank is scored along lines l, 2, 3, and 4 to provide a frontWall ID, a cover l3, rear wall 42 and bottom wall I l.

The front wall I0 is provided with free end flaps 9 and i5 separatedfrom the adjacent flaps by slit lines 6 and 1. Flaps 9 and 56 are slitalong lines 23 and 23'. Rear wall I2 is provided with end fiaps i9 and20 separated from adjacent flaps by slits 26 and 28, and 25 and 21,respectively. Flaps l9 and 20 are provided with tongues 24.

The cover l3 is provided with inner end flaps 2i and 22. The bottom H isprovided with inner end flaps l1 and 48. One end of the carton isadapted to be closed by overlapping inner end flaps i8 and 22, andinterlocking thereover outer flaps 3 and 20 by inserting tongue 24through slit 23. The other end of the carton is adapted to be closedsimilarly by folding inner flaps H and 2! in overlapping relation andthen looking outer overlapped flaps l5 and I9 by means of tongue 24extending through slit 23.

The cover l3 has a flap extension for providing a composite sealing fiapconsisting of adjacent panels i4, 35 and 36 formed by score lines 30 and40. Panel l4, designated as extension panel, is hinged to the cover 13along score line 4. Panel 35, designated as outer grasping panel andpanel 36 as inner grasping panel, are of substantially the same width. Aseries of spaced glue tongues 42 are provided along the free edge ofpanel 36 and integral therewith along score line 4|. Score lines 30 and4! are partially cut through the blank as shown in Figure 4, for apurpose to be ex plained later.

In making the carton for use, the flap extension is folded back onitself so that panels 36 and tongues 42 are folded over on panels l4 and35 along score line 40. The folded-over abutting faces of graspingpanels 35 and 36 are preferably glued together by adhesive 65. The innerfaces of tongues 42 are also preferably glued to the overlapped portionsof extension panel M. The glue tongues 42 are then glued by adhesive 66to the upper edge of the front wall to as shown in Figures 3 and 4.

The free edges of the panels I4, 35, and 36 constituting the extensionon cover l3 are preferably sloped toward each other as shown in Figure 1so that the grasping panels will be els 35 and 36 to be spaced awayslightly from the ends of the carton as shown in Figure 3.

The cartons are shipped by the carton manufacturer to the carton user inknocked-down flat condition with the extension on cover l3 folded andglued to the'front wall l as previously described.

In use the carton is folded up into its rectangular condition as shownin Figure 5. One end of the carton is closed by means of the end fiapspreviously described and ice cream or other comestible to be frozentherein is introduced at the other open end. After being filled this endis closed and the carton transferred to the hardening room. The front ofthe carton will have the appearance shown in Figure 3.

When the consumer is ready to use the contents within the carton bothends of the carton are first opened by disengaging the interlocked outerflaps 9 and 20, and i5 and I9 at each end. The grasping panels 35 and 3Bare then seized by the fingers as shown in Figure 5 and pulled back soas to tear the glued tongues 42 free from the front wall [0. The cutscore line 4| permits ready peeling or separation of the glued tongueportions from the front wall Ill. The contents of the carton will thenbe left freely exposed resting upon the bottom H of the carton.

The construction of the extension panels and score lines as previouslydescribed facilitates the ready grasping of the grasping panels andtearing open of the carton without peeling the fibrous stock material.Score lines 30 and 4| facilitate bending up of the grasping panels asshown in Figure 5. By virtue of the glued tongue portions 42, thegrasping panels are readily separated and torn away from the front wall[0. There will be no peeling of the carton blank on the inside of thecarton because the fibers cannot peel beyond the upper outer edge of thefront wall l0 when.

the carton is opened as the fibers on the inner faceof the tongues arediscontinuous with the fibers of the overlapped portion of the frontwall. The partially cut score bulging at the fold thereby giving acompact and neat appearance to the grasping panels.

The carton construction thus provides a carton made from a single blankof paper board having a cover provided with an integral extendingsealing flap which serves to seal the carton.

This flap consists of panels [4, 35, 35, tongues 42 integral with panel36, and is folded and secured to itself as previously explained so as toprovide inner and outer grasping panel portions.-

The inner faces of the tongues 42 are adhered to an overlapped portionof the adjacent wall by means of glue applied to the inner faces of thetongues. The score lines 30 and 4| on the sealing flap provide hingedgrasping portions for tearing open the sealing flap.

Many modifications may be made in the carton construction. For example,as illustrated in Figline 40 also permits panfolded compactly without;

edge to provide tongues ures 6 to 9, an auxiliary tab portion 50 may beprovided integrally hinged to outer grasping panel byslitting panel 36in its medial region along slits 5| and 52 as shown in Figure 6. Thepanels I4, 35, 36 are folded and glued together as previously describedin connection with the carton construction shown in Figure 1. Thetongues 42 are then glued to the front wall and the auxiliary tab 50 ispositioned in extended relation asillustrated in Figure 8. When it isdesired to open the carton, grasped by the fingers as shown in Figure9'and the carton is opened by pulling the glued tongues 42 free from thefront wall. In this modification, if desired, the tongues may bereplaced by a continuous glue panel.

Anothermodified construction is illustrated in Figures 10 to 12, whereinin addition to panels I4, 35 and 36 previously described, there isprovided an additional glue panel 42' 42. These tongues 42 I are gluedto the front wall of the carton. This I tions of the adjacentconstruction serves to ensure a leak-proof joint at the region where thetongues are glued to the front wall.

It is to be understood that other variations and modifications of thespecific embodiment disclosed are intended to be included within thescope of the appended claims.
